automatic order-picking system / pick-to-light
The PTL (Pick to Light and Put to Light) systems are picking solutions of the operator to materials kind that ensure high output (up to 500 - 600 picks per hour). The operator moves along the shelves (dynamic and with multiple accumulation depth) and picks the whole amount of materials required for a batch of orders through signals that appear on lit monitors. Practically speaking, the picker immediately subdivides the materials in different cartons, each of which is associated to a picking list that is being filled.
The system can move empty cartons towards the operators and transfer the cartons to other operator areas or end-of-line as they are filled. Matching a progressive number to each box guarantees the traceability required by activities downline (weighing, packing list, label printing, final destination).
